Components description of steel door frame machine
1. Guide device
Feeding material guide device, use high speed steel on both sides; its feature of
High hardness, high wear resistance and high heat resistance to guarantee long life of machine. 
2. Rollers of machine for making rolling doors
All Rollers manufactured from 45# steel
CNC machines can improve rollers precision.
Chromate finish on surface to add hardness of rollers.
3. High Accuracy Shafts
Solid shafts dia. 80mm for different material thickness.
All shafts are tooled twice by cylindrical grinding machine to ensure final precision.
Guarantee buyers get high accuracy deck sheet from Zhongyuan made machine.
Design bearings inside the rollers to allow machine run with less loading so that rollers not easy to damage.
Ensure the same speed between all the rollers, no speed difference between rollers, improve the forming accuracy.
Bearings are helping to prolong machine life. Our made forming machines are allowed using more 15 years.
5. Main door frame makingmachine body
Door making machine frame made from H450 type steel by welding
Side wall thickness: Q235 with thickness of 20mm
Grooves are designed between the connection-wall to prevent movement of the connect-wall and enhance stability.
The material for Embossing roller: bearing steel GCr15 for long working life, heat treatment
Motor Driving, Gear /Sprocket driving transmission, about 44-steps forming stations
Main Motor=7.5kw*3, Frequency speed control
All the screw bolts with grade 8.8(Some other factories use low grade4.8) to ensure fix the machine structure tightly and long life during the machine running.
Forming speed 15m/min.
All processed rollers are assembled on the carpet to avoid scratching on the rollers' surface.
6. Automatic Cutting system
Post to cut, stop to cutting or no-stop cutting for option .
All cutting frame are heat treatment to remove the original stress of steel, reduce deformation, improve stability .
Cutting tool material: Cr12MoV,hardness can reach 58-60Hrc.
Machine can cut as buyers wanted sheet length,full automatically.
Hydraulic station provides power for cutting. Motor cutting for option .
7. Automatic PLC Control System
Control The Quantity And Cutting Length Automatically
Input the production data(such as production quantity,Length,etc.)on the touch screen , machine can finish the set production plan automatically.
One time buyer can set 20 batch data in the programme.
